--- Comment #7 from Jan Hubicka <hubicka at gcc dot gnu.org> 2012-03-25 10:14:40 UTC ---
Hmm, partitioning seems right.
We get into ltrans0:
cfliteValueCallBacks: availability:not-ready (asm: cfliteValueCallBacks) needed
analyzed finalized externally_visible prevailing_def in_other_partition
  References:
  Refering this var:  fn:main/0 (addr)

that is only alias from other partition. We however somehow work out the alias:

cfliteKeyCallBacks: availability:not_available (asm: cfliteKeyCallBacks) needed
  References:
  Refering this var:  var:cfliteValueCallBacks (alias)

and then output it with 0 initialization.  Seems overactive alias processing
somewhere.
